Abstract (en)
[origin: US2011195673A1] A wireless communication unit includes a transmitter, a receiver, a selectivity element and a baseband processing module. The receiver has at least one summation module arranged to add a cancellation signal to the quadrature baseband receive signal. a baseband processing module arranged to: receive the quadrature baseband transmit signal and quadrature baseband receive signal; apply independent gain and phase adjustments to quadrature portions of the quadrature baseband transmit signal, based on at least one signal component of the quadrature baseband receive signal, to form independent cancellation signals; and apply the independent cancellation signals to the at least one summation module.
